Nelson, a Democrat, links the hunt for illegal voters with the 2000 election — before anyone even uttered the word "recount" — and Florida's botched attempt to remove felons from the rolls ahead of Election Day.

He warned Scott about repeating the ordeal in a letter.

"In the 2000 Florida election, at least 1,100 eligible voters were wrongly dropped from voting rolls in an attempt to purge a list of felons," Nelson wrote. "Many of those who were dropped showed up to vote and were told they could not. And in a presidential election decided by 537 votes, that erroneous purge may have been a factor."

PolitiFact Florida wanted to compare the millennial purge with the most recent one, which has produced three federal lawsuits.

We'll examine the parallels and determine if Nelson offered an accurate recap.

2000

As part of their 1998 elections reforms, state lawmakers told the Department of State to remove felons and other ineligible voters from the rolls after thousands of corrupt votes, including 100 votes by felons, were cast in a Miami mayoral election.

The agency hired Boca Raton-based DTS Technologies, a subsidiary of ChoicePoint in Atlanta, for about $4 million to produce a list of probable and possible felons before the election. (Unlike most states, in Florida a felon's civil rights are not restored unless he or she is granted clemency by the governor and Cabinet.)

The company warned the state that many people on the list would not be felons, but officials wanted DTS to use broad parameters — that meant more felons off the rolls.

People whose names appeared on the list of more than 50,000 names had to prove their innocence or automatically be dropped from the rolls within several weeks of receiving written notice. Twenty counties ignored the state's directive because they found the data unreliable, including the Madison County elections supervisor, who found her own name among suspected felon voters.

News organizations unearthed numerous accounts of law-abiding citizens turned away at the polls because they could not prove their innocence. Several thousand people appealed to the Florida Department of Law Enforcement, and half were found to not be felons.

The precise damage is pretty hard to calculate.

"I've seen numbers all over the map," said Myrna Perez, senior counsel in the democracy program at the Brennan Center for Justice, which is investigating the purge ordered by Scott.

Nelson's figure comes from a 2001 Palm Beach Post investigation, the crux of which asserts at least 1,100 eligible voters were wrongly purged before the 2000 election — "the collateral damage from an aggressive and ill-conceived state plan to prevent felons from voting."

The Post's count included at least 108 citizens who were cleared after the election and 996 people who committed felonies in other states (they were supposed to retain their civil rights even in Florida).

Other tallies put the number of bad targets 11 or 20 times higher.

The NAACP and American Civil Liberties Union sued the state in 2000 partly over the felon voter purge, arguing it disenfranchised black voters. A consent decree from the lawsuit settlement required the state to run its old felon lists with new standards.

The exercise resulted in 12,023 fewer Floridians making the felon list, meaning these people could have been targeted as felons and denied the right to vote, reported the St. Petersburg Times (now the Tampa Bay Times) in 2003.

Some caveats: This figure does not mean 12,000 people were purged without cause. It means they could have been. Plus, some people within this class might not have been affected anyway because some supervisors decided not to enforce the purge.

A massive story about the 2000 election by Vanity Fair identified 20,000 people who were wrongly included. We don't know where that number comes from and will update this story if we find out.

Nelson should have used that much bigger figure, said Leon County Supervisor of Elections Ion Sancho.

"I read the letter from Nelson and I laughed," Sancho said. "How come you didn't vet this better? You could have had a way bigger number."

2012

Twelve years later, Gov. Scott ordered state officials to clear the rolls of noncitizen voters.

The state department whittled a list of 182,000 potential noncitizens to about 2,700 by comparing driver's license data, which contains some citizenship data, against voter rolls. County supervisors, again, were told to notify those listed by mail of the need to urgently prove their citizenship. And also like last time, some supervisors decided to sit out the purge.

Already, a Pasco County woman and a 91-year-old World War II veteran from Broward County have made headlines for being wrongfully targeted. In fact, elections supervisors found that most names on the list belong to citizens — probably because the motor vehicle department's citizenship information is out of date, the Miami Herald reported.

Republicans stand by the clean-up efforts.

"The implication of Nelson's letter is that eligible voters will not be able to vote, yet there is no evidence of this," said Kristen McDonald, RPOF spokeswoman.

Rolling Stone waded into the issue with a scathing report, quoting Sancho as saying, "Those of us who have been here long enough get this eerie similarity to the flawed felon databases of 2000 in Florida."

The statement

"In the 2000 Florida election, at least 1,100 eligible voters were wrongly dropped from voting rolls in an attempt to purge a list of felons. Many of those who were dropped showed up to vote and were told they could not."

The ruling

Nelson precisely cites a Palm Beach Post analysis that put the total number of people wrongfully dropped from the voter rolls in 2000 at about 1,100. Subsequent estimates were much higher, but he qualifies his figure with "at least." We rate his statement True.
